STOVE.

SPECIFICATION forming part of Letters Patent No. 481,226, dated August23,1892.

Application filed March 18, 1892.

To all whom t may concern.-

Be it known that I, IsAAc DE HAVEN, a citizen of the United States,residing at Allegheny, in. the county of Allegheny and State ofPennsylvania, have invented or discovered a certain new and usefulImprovement in Stoves, of which improvement the following is aspecification.

The invention relates to certain improvements in stoves of that class orkind wherein the front of the stove is closed by a verticallymovabledoor.

It has heretofore been customary to employ weights arranged at the sideof the stove and connected by chains passing over guide-pulleys at thetop of the stove to the top of the door to support the latter inits'elevated position. This class or kind of stoves has generallyincorporated therewith a plate known as a deiecting-plate, which is sosecured in the stove that the products of combustion are caused totraverse the upper part of the stove before reaching the iiue.

It is the object of the present invention to utilize thisdeiiecting-plate as a counter-balance for the door.

In general terms the invention consistsin the construction andcombination substantially as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure l is a sectional elevation of a stove having my improve- 'mentapplied thereto, the door being shown in its elevated position and thedetlectingplate in such position as to cause the circuitous traverse ofthe products of combustion. Fig. 2 is a similar view, the door beingshown closed and the detlecting-plate in an elevated position; and Fig.3 is a detail View showing the deiiec'ting-plate in plan.

In the practice of my invention the stove proper is constructed in anyusual or suitable manner and the sliding door lis mounted thereon in thecustomary way. This door is provided at its lower edge withinwardly-projecting arms 2, which are connected by links 3 with the arms4, projecting from the deiiecting-plate 5. As shown in the drawings, thedetlecting-plate is provided with pivotal Serial No. 425,412. (Nomodel.)

pins 6, which are mounted in suitable bearings in the side of the stove,such bearings being so located that the rear edge of the deecting-platewill when in its lowered position rest upon the back lining of thestove, as shown in Fig. l. The armst project forward toward the front ofthe stove and are preferably made of such a length that when thedetlecting-plate is in its horizontal position the inner ends of saidarms will be in line, or nearly so, with the inner ends of the arms 2,so that when the detlecting-plate is depressed the arms 5 will exertapractically straight upward pull on the door. The body portion of thedetlecting-plate is made sufliciently heavy to counterbalance the weightof the door, so that the latter maybe retained in an elevated positionor any point intermediate between that and its closed position.

It will be observed that by connecting the door and deflecting-plate inthe manner described the closing of the door will raise the detlectingplate, and thereby opena direct passage for the products of combustionto the outlet-flue. When the door is raised, the deecting-plate will beshifted to the position which it normally occupies and the products ofcombustion will be caused to traverse the upper portion of the stovebefore reaching the outlet-flue.

I claim herein as my invention- I. In a stove, the combination of avertically-moving door and a movable deflectingplate connected theretoand adapted to serve as a counter-balance for the door, substantially asset forth.y

2. In a stove, t-he combination of a vertically-movable door and apivoted deflectingplate provided with forwardlyprojecting arms connectedto the door,whereby thelatter is adapted to serve as a counter-balancefor the door, substantially as set forth.

In testimony whereof I have hereunto set my hand.

ISAAC DE HAVEN.
